Abstract

Les dispositifs de retenue de poussoir classiques pour pompe d'injection de combustible comprennent en général un passage radial borgne formé en poussoir. Une seule ouverture du passage est disponible pour l'insertion et le retrait d'un roulement à billes ou d'un ressort et la tige d'arrêt qui doivent être maintenus en place avant que le poussoir soit inséré dans un alésage de logement. Dans une telle configuration, le roulement à billes ou le ressort comprimé et la tige d'arrêt ont tendance à sortir et à tomber avant que l'ouverture du passage soit fermée par une paroi interne de l'alésage de logement. On décrit un dispositif de retenue de poussoir (10) amélioré qui comprend un logement (16), un poussoir (18), un dispositif d'arrêt (22), et un dispositif de sollicitation (24). Le poussoir (18) comprend un passage interne (44) qui permet d'introduire le dispositif d'arrêt (22) et le dispositif de sollicitation (24) dans leur position de montage final dans le passage intérieur (44) alors que le poussoir (18) est déjà inséré dans un alésage (28) du logement (16).
